Abstract

Techniques for wireless network discovery and selection support are described. In one embodiment, for example, an evolved packet core (EPC) node may comprise a processor circuit to implement an access network discovery and selection function (ANDSF) according to a management object that includes a branch comprising one or more policies to select a wireless local area network (WLAN), the processing circuitry to receive capabilities information and location information for a user equipment (UE) and determine access network information for the UE based on the capabilities information and the location information. Other embodiments are described and claimed.

Claims

1. An apparatus for use in a user equipment (UE), comprising:

logic, at least a portion of which is in hardware, the logic to;

discover a set of wireless local area networks (WLANs);

identify a WLAN selection policy (WLANSP) rule comprised in an access network discovery and selection function (ANDSF) management object (MO) for the UE; and

select a WLAN from among the set of WLANs based on one or more WLAN selection criteria associated with the WLANSP rule.

2. The apparatus of claim 1, the one or more WLAN selection criteria to be specified by one or more nodes comprised in a selection criteria sub-branch of a WLANSP branch of the ANDSF MO for the UE, each of the one or more nodes to substantially match a respective one of one or more nodes defined in HotSpot 2.0 Release 2.

3. The apparatus of claim 1, the one or more WLAN selection criteria to include at least one WLAN selection criterion specified by a PreferredRoamingPartnerList node.

4. The apparatus of claim 1, the one or more WLAN selection criteria to include at least one WLAN selection criterion specified by a MinBackhaulThreshold node.

5. The apparatus of claim 1, the one or more WLAN selection criteria to include at least one WLAN selection criterion specified by a RequiredProtoPortTuple node.

6. The apparatus of claim 1, the one or more WLAN selection criteria to include at least one WLAN selection criterion specified by an SPExclusionList node.

7. The apparatus of claim 1, the one or more WLAN selection criteria to include at least one WLAN selection criterion specified by a MaximumBSSLoadValue leaf.

8. The apparatus of claim 1, the ANDSF MO to comprise a home network preference branch containing an S2aConnectivityPreference leaf comprising a value to indicate whether a home operator of the UE prefers the UE to use S2a procedures to establish packet data network (PDN) connections over WLANs.

9. The apparatus of claim 1, further comprising:

at least one memory;

at least one radio frequency (RF) transceiver; and

at least one RF antenna.

10. At least one non-transitory computer-readable storage medium comprising a set of instructions that, in response to being executed at user equipment (UE), cause the UE to:

send an access network information request over an S14 interface connection;

receive access network information over the S14 interface connection in response to the access network information request; and

select a wireless local area network (WLAN) based on the access network information and on a plurality of WLAN selection criteria specified by a WLAN selection policy (WLANSP) rule defined in an access network discovery and selection function (ANDSF) management object (MO) for the UE.

11. The at least one non-transitory computer-readable storage medium of claim 10, comprising instructions that, in response to being executed at the UE, cause the UE to:

identify a plurality of available WLANs based on the access network information; and

select the WLAN from among the plurality of available WLANs based on the plurality of WLAN selection criteria.

12. The at least one non-transitory computer-readable storage medium of claim 10, comprising instructions that, in response to being executed at the UE, cause the UE to determine at least one of the plurality of WLAN selection criteria based on a PreferredRoamingPartnerList node comprised within the ANDSF MO for the UE.

13. The at least one non-transitory computer-readable storage medium of claim 10, comprising instructions that, in response to being executed at the UE, cause the UE to determine at least one of the plurality of WLAN selection criteria based on a MinBackhaulThreshold node comprised within the ANDSF MO for the UE.

14. The at least one non-transitory computer-readable storage medium of claim 10, comprising instructions that, in response to being executed at the UE, cause the UE to determine at least one of the plurality of WLAN selection criteria based on a RequiredProtoPortTuple node comprised within the ANDSF MO for the UE.

15. The at least one non-transitory computer-readable storage medium of claim 10, comprising instructions that, in response to being executed at the UE, cause the UE to determine at least one of the plurality of WLAN selection criteria based on a SPExclusionList node comprised within the ANDSF MO for the UE.

16. The at least one non-transitory computer-readable storage medium of claim 10, comprising instructions that, in response to being executed at the UE, cause the UE to determine at least one of the plurality of WLAN selection criteria based on a MaximumBSSLoadValue node comprised within the ANDSF MO for the UE.

17. The at least one non-transitory computer-readable storage medium of claim 10, the ANDSF MO for the UE to contain a WLANSP branch, the WLANSP branch to include:

a selection criteria sub-branch comprising the plurality of WLAN selection criteria; and

a ValidityArea node specifying one or more location conditions for the WLANSP rule.

18. An apparatus for use in a user equipment (UE), comprising:

logic, at least a portion of which is in hardware, the logic to;

select a wireless local area network (WLAN) from among a plurality of discovered WLANs based on a set of WLAN selection criteria, the set of WLAN selection criteria contained in a selection criteria sub-branch of a WLAN selection policy (WLANSP) branch of an access network discovery and selection function (ANDSF) management object (MO) for the UE; and

establish connectivity to a packet data network (PDN) via the selected WLAN.

19. The apparatus of claim 18, one or more of the WLAN selection criteria defined by a PreferredRoamingPartnerList node comprised in the selection criteria sub-branch.

20. The apparatus of claim 18, one or more of the WLAN selection criteria defined by a MinBackhaulThreshold node comprised in the selection criteria sub-branch.

21. The apparatus of claim 18, one or more of the WLAN selection criteria defined by a RequiredProtoPortTuple node comprised in the selection criteria sub-branch.

22. The apparatus of claim 18, one or more of the WLAN selection criteria defined by a SPExclusionList node comprised in the selection criteria sub-branch.

23. The apparatus of claim 18, one or more of the WLAN selection criteria defined by a MaximumBSSLoadValue node comprised in the selection criteria sub-branch.

24. The apparatus of claim 18, the set of WLAN selection criteria to be specified by a set of nodes comprised in the selection criteria sub-branch, each of the set of nodes to correspond to a respective node defined in HotSpot 2.0 Release 2.
